Elegant sea slug (Paul Naylor)
Elegant sea slug (Okenia elegans)
Sea slugs are an amazingly colourful bunch of creatures compared with their land-based counterparts. Belonging to the order nudibranch meaning ‘naked gill’, sea slugs have no shell or mantle to protect them or to retreat into. However, they are able to defend themselves successfully by producing toxins and irritants from special skin glands.
